Launching a Squash Bug Campaign

You know you’re a plant geek when you lounge poolside, frozen watermelon mint lemonade in hand and research organic methods of trapping squash bugs.

One google search “Are squash bugs attracted to light?” brought a positive result.

Gardeners reported their porch lights attracted squash bugs and this got my wheels turning.

Maybe I could create a trap that lured squash bugs using a light source and somehow keep them from crawling back out.

So I took a large plastic soda bottle and cut the top one-third off. This funnel shape would be placed spout side down into the bottle. I had tiny tea lights that I could use as a light source and put one at the bottom.

With luck, the squash bugs would see light at the end of the funnel and follow it to their demise.

Then I headed to the community gardens. Martel gave me the OK to use her plot for the experiment. We caught squash bugs there in the last two days.

I was concerned the squash bugs, because of their size, could manage to get out of the trap so I used sticky Tanglefoot to coat the outside of the funnel. This helped also to create a seal between the funnel and the side of the bottle.

Next, I put some tape strips around the bottle to give the squash bugs something to crawl on. A ‘pathway’ to the top of the bottle and into the trap just in case the plastic bottle is too slick for them to cling to.

I dug a hole and inserted the base of the bottle. The hole is under the zucchini leaves as this is where squash bugs hang out.

Now, I wait.

Tomorrow morning I will head to the farm and count how many bugs we catch.

Our other experiment, the yellow cup faux blossom traps caught near 100 cucumber beetles in one plot alone.

 

 

Eradicating Squash Bugs

Hi gardeners – I just got back from the gardens and all-in-all things look good.

We discovered squash bugs this week.  Mary Beth shared this great image of them:

These are the eggs they lay on the underside of leaves.

If you find the eggs, remove them with your fingernail or with a piece of duct tape wrapped inside out around your finger. Take them out of the garden and discard.
The next step would be to spray with diatomaceous earth (DE).  I left two full spray bottles on the counter. Shake well before using and spray both sides of the leaves only. Not the flowers. We don’t want to hurt our bees.
What damage do squash bugs do?
This insect feeds by sucking the sap of plants and in the process infecting plants with toxins that lead to the plant’s demise. Our best defense is to stay on top of it, remove the eggs and use DE.
If you see something in the garden and need information, contact me.
Observations
A few gardeners need to get to their weeding.  And, a few others, who have let their plants go to seed, may want to pull the flowering broccoli rabe, lettuce or arugula and plant a new crop.  Once they are flowering, the taste is more bitter.
I will be in the garden Thursday from 8 a.m. to 11 a.m. And I will be teaching another class Saturday morning at 9:30.
Hope to see you in the gardens,
Natalie Walsh, Garden Director
